  • Patent number: 11916612
    Abstract: An object of the present invention is to provide a mobile terminal capable of predicting fluctuation in communication quality. The mobile terminal according to the present invention uses terminal information consisting of position/orientation/speed/component operation/control command information/camera information/sensor information, and the like of the mobile terminal to model a relationship with communication quality and predict the communication quality using the obtained communication quality prediction model. When fluctuations in communication quality can be predicted, it is possible to cope with the fluctuations (especially deterioration) in communication quality in advance (for example, to change a communication destination station, to decrease a data rate in an application, or to change a control mode of a terminal to a safer mode, by knowing in advance deterioration in quality of a radio signal).

  • Publication number: 20220345919
    Abstract: An object is to provide a wireless terminal and a communication quality prediction method for enhancing the versatility of communication quality prediction. In the wireless terminal and the communication quality prediction method according to the present invention, objects are extracted from surrounding environment information such as a camera image collected by a surrounding environment information collection unit, the objects are classified into predetermined categories (for example, whether the extracted objects are persons or machines or whether their moving speeds are high or low), and an image is reconstructed for each category. It is possible to predict communication quality based also on, for example, operations or materials of the objects, by performing machine learning of the communication quality after reconstructing the image for each category.
